fusion reactors

Ironically the new generation reactors are the solution to the hydro issue. Wind and solar are just not efficient enough and take up far too much real estate. The intrum step is barium reactors which are compact and very safe. Germany gets it and have gone extensively atomic for electricity and they are clean, safe and can produce power far cheaper than the so call green alternatives.

Fission will be the real game changer when they learn how to control that beast.

I think you have the 2 mixed up, current reactors are fission reactors (splitting of atoms) and the future is fusion reactors.

This is what I was thinking of as the way to power aircraft of the future electrically

As much as I wish that were the current state of the art when it comes to fusion, the truth is we haven't managed to build a fusion reactor that actually produces more energy than it consumes yet, but that's another thing I hope I'll live to see become reality. The best candidate on the horizon so far is the massive multinational ITER reactor project in France (which Canada opted out of participating in, I might add). That one weighs somewhere north of 23,000 tons.

Now I have been reading about compact fission reactors lately, but I suspect the steam turbines and associated machinery required to convert any fission reactor's output to electricity would be far too large and heavy for an aircraft.

My guess for now, is that it'll be batteries powering electric aircraft, or possibly some sort of fuel cell as an interim step.

ZeroAvia is already flying a hydrogen powered Malibu. It is a hydrogen fuel cell that powers the electric motor.

Oxidation of the compressed hydrogen takes place electrochemically during which time the hydrogen atoms react with oxygen atoms to form water; in the process electrons are released and flow through an external circuit as an electric current to the motor to drive the propeller.

If you run the electrolyser with renewable energy such as wind and solar, the process is carbon free.

Nice. Between fuel cells and straight battery implementations, I imagine these are what most of the electric aircraft attempts will look like for now, which is a similar pattern to the path taken for electric cars. Realistically, electric cars might still be in that early stage now if it weren't for Musk.

I notice from the ZeroAvia web site that they plan on using electrolysis to produce their hydrogen, using wind and solar. While that does help them claim that their process is renewable (with all the usual caveats about manufacturing), I'm not sure how scalable it's going to be. It's probably good enough for a test program like this one, but if they plan on pitching hydrogen as a serious contender, someone's going to have to come up with a far more efficient method that scales up to match the needs of the aviation industry.

Near-term, I'm hoping for a breakthrough in solid-state battery research which would greatly impact electric vehicles of all kinds.

I live in Scotland and it's starting to get some real buzz going here. Distribution to aviation from private sector is not a giant leap…

Make no mistake, the Q400 is just a god awful airplane. I think what I hate most about it is the air conditioning - When the bleeds aren't sending smoke from burning oil into the cabin (this is an alarmingly regular occurrence), the ACMs simply do a terrible job regulating the temperature in automatic mode, and if you put them in manual, moving the knob the width of a hair will roast you or freeze you. Every time you change power settings down in the 10-40% torque range the bleeds change from 2.2 - 2.7 - 3.0 making the airflow erratic and noisy and very distracting and very very fucking irritating. Also, if you shut the airplane down without the pack knobs in the 12 o'clock position, wherever you left them will become the new "12 o'clock" next time you turn them on. On installation day a crew of 4 men arrived with a truck. They prepared my roof for mounting hardware, dug a trench for electrical conduit (needed for DC wiring from my detached garage), mounted the power inverter on the outside wall of my home, installed panels, wired up everything and tested. The whole installation needed about six hours to complete. Cause of this option I'd chose https://a1solarstore.com

I can just see the jobs adds now:

"500 hrs electric airplane PIC required"

Yeah how much electric time do ya got?

Germany is also a sucker for green washing. https://nationalpost.com/opinion/np-vie ... ail-target

There are flight schools in Europe using the Pipstrel for primary flight training. they will have instructors with lots of electric time.
